ABSTRACT
The jatropha is becoming increasingly important due to diminishing petroleum reserves and adverse environmental consequences of exhaust gases from petroleum fueled engine. The use of jatropha oil as alternate fuel demands the processing of oil to remove the gums to avoid filter choking and carbon depositions on engine. The investigation was carried for optimization of degumming process parameters of crude jatropha oil. The Jatropha carcus oil was extracted from commercial screw type expeller. The extracted crude oil was degummed under different process conditions i.e. hot water concentration(1,2,3 and 4%), reaction temperature( 50,60,70 and 80 0C), reaction time (20,40,and 60 minutes), agitation duration (10,20,30,40 and 60 minutes). The efficiency of degumming was evaluated based on the yield of lecithin(VV-1).The maximum yield of lecithin was found 3.9%. The optimum quantity of water required for complete hydration of lecithin was 3 percent of oil. The reaction temperature beyond 70 0C has not shown any improvement in lecithin recovery.
Key words :
Gums, Jatropha oil, lecithin, phosphatides, water degumming.
